Other claims from this paper (7)
- Association The 5 cm irrigation treatment gave the highest number of ear bearing tillers per plant (24).
- Association The 5 cm irrigation treatment gave the highest number of filled grains per panicle (72).
- Intervention effect Pretilachlor followed by chlorimuron-ethyl plus metsulfuron-methyl gave the minimum weed density and weed dry weight among the weed management systems tested.
- Intervention effect The same pretilachlor-based weed management gave higher weed control efficiency than the other systems.
- Intervention effect The same weed management gave significantly higher grain yield of 5.45 t/ha.
- Intervention effect The same weed management gave the highest net return (? 41, 441/ha).
- Intervention effect The same weed management gave the highest B:C ratio (2.17).
